Brines Across the Solar System


The LPI’s Brines Across the Solar System (BAS) initiative dives into brines as a planetary process, from modern to ancient brines and the technologies needed to explore them. Salty aqueous solutions (i.e., brines) are prominent across diverse planetary bodies. They are observed in the gas plumes presently erupting from Enceladus, reconstructed from precipitates on the surface of Ceres and Mars, and inferred from meteoritic samples. Understanding the mechanisms that led to the formation and preservation of these brine systems provides vital clues to their role in geological, geophysical, environmental, and biological processes. In this three-part conference series, we will address questions relating to the thermodynamics and physiochemistry of brines, as well as their occurrence today and throughout time in our solar system and beyond.
